In a presentation to the Society for General Microbiology meeting at Harrogate International Centre, today (Monday 30 March), Dr Heike Schmitt from the University of Utrecht, the Netherlands described how antibiotics passed from the animals in manure that was then spread on farmland. Although higher organisms, such as earthworms, would only be affected at unrealistic concentrations of antibiotics, changes in soil bacterial communities have been found repeatedly using molecular microbiological techniques. http://www.physorg.com/news157637559.html Biology Mon, 30 Mar 2009 13:13:08 EST news157637559 The New Economic (In)Security of Seniors, issued today by the Institute on Assets and Social Policy (IASP) at Brandeis University finds that Massachusetts seniors face widespread financial insecurity. Almost 7 in 10 senior households in Massachusetts lack sufficient resources for long-term economic security, according to the study.

However, a century ago, red deer were imported from continental Europe to the island of Otterøya in Namsos, and these imported deer have created hybrid forms with the Norwegian red deer on the island. These hybrids have only to a modest degree become integrated with the rest of the Norwegian red deer population. http://www.physorg.com/news157132839.html Biology Tue, 24 Mar 2009 17:01:08 EST news157132839 CD is a highly prevalent disease (1:100 to 1:300) which fulfils most of the criteria favoring mass screening.

Jewish people traditionally settled in South Florida for economic opportunities, for the climate, to join friends and family and to retire. Nonetheless, the once growing Jewish population of Broward County is now declining in numbers, according to a recent study conducted by University of Miami professor Dr. Ira M. Sheskin, from the department of Geography and Regional Studies in the College of Arts and Sciences and director of the Jewish Demography Project of the Sue and Leonard Miller Center for Contemporary Judaic Studies. http://www.physorg.com/news155925817.html Other Sciences Tue, 10 Mar 2009 17:44:11 EST news155925817 Breed a better crop of wheat? That's exactly what a team of researchers from Kansas State University and the U.S. Department of Agriculture hope their research will lead to. In their study, appearing in the March 2009 issue of the journal Genetics they analyzed the type of wheat commonly used to make bread in an effort to understand why it is versatile enough to be used around the world and across different climates. This analysis provides important insights into why its genetic structure gives it a tremendous advantage over other competing species. Further, their analysis provides an important first step toward improving wheat crop yields to levels that can support ever-growing populations of people. http://www.physorg.com/news155912627.html Biology Tue, 10 Mar 2009 14:04:10 EST news155912627 A University of Colorado at Boulder research team has identified a type of skeletal muscle stem cell that contributes to the repair of damaged muscles in mice, which could have important implications in the treatment of injured, diseased or aging muscle tissue in humans, including the ravages of muscular dystrophy. http://www.physorg.com/news155482971.html Biology Thu, 05 Mar 2009 13:43:26 EST news155482971 Sick or injured African-American patients wait about an hour longer than patients of other races before being transferred to an inpatient hospital bed following emergency room visits, according to a new national study published in the journal Academic Emergency Medicine.
